Figure 3 Time course study on the functional properties of the guinea pig skin with allergic contact dermatitis. Changes in various instrumentally measured parameters observed in allergic contact dermatitis induced in C. albican-immune guinea pigs by application of 1:200 Candida antigen for 24 h under occlusion. These parameters are (a) redness score a*, (b) incidence of epidermal cells in a DNA synthesizing phase, (c) TEWL, and (d) skin surface pH.
